Why do we need to login to see the status page?
How would we learn about status in case of auth-adjacent incident?
I assume it's related to their reasoning for the outage in the first place... "increased load", which to me sounds like a DDoS.
The login redirect probably stops a lot of the traffic, and from closer to the edge of their network.
you don't need to, https://status.cloud.microsoft/. there is a public version
There are logged in pages for people to raise tickets, see specific services/regions they have access or restricted ones(Gov/Sovereign Cloud only available to some users) and also other features only logged in users would need.
Yeah it will not work under an auth downtime or the service application downtime, but it is not designed for that.
It is for for the items which are localized at service/DC/region level. The service app pages on azure covers planned maintenance, retirement of old services, security advisories and so on.
